The theme of this piece of music consists of four symmetrical phrases with distinct levels and vivid images. The endings of the first, second and fourth sentences are gradually descending, and the ending of the third sentence, which plays the role of tone sandhi, has a positive and optimistic mood. In addition to the theme, the whole song has five variations and reappearance. Through the use of different playing skills, the composer endowed the variations with different personality characteristics. The first variation adds a variety of rhyming techniques to the left hand on the basis of the theme section, and the melody is euphemistic and delicate, full of charm. The second variation is free variation under the guidance of strict variation thinking, and musical thinking is carried out in the form of folk songs. The third variation is 3/4 beat, and the right hand plays a long singing melody, which is beautiful and clear, as if telling the beautiful scenery of hometown, and my heart is full of infinite pride. After the theme reappears for a period of time, the music enters the final variation, and the left hand plays the backbone sound of the theme with octaves in the bass area, which is firm and decisive. On the basis of maintaining the original structural integrity, the right hand uses the common technique of "theme adding flowers" in folk music to make variations in the high-pitched area, and with the speed of Allegro, it produces the sound effect of "endless movement".
